Title: Ship storage tanks
IPC: B63J2/08
Filed: 1973-06-06
Abstract: 1439862 Venting ships' tanks D J SEYMOUR N MACRITCHIE P J MATTHEWS and T A CLARK 6 June 1973 [14 June 1972] 27108/73 Heading B8V A vent tube 30 for a ship's tank includes a valve member 32, normally held open by a latch 33/40 against the closing action of a spring 37, pressure-responsive means 43-54 automatically releasing the latch when subjected to the continued hydrostatic pressure exerted in the event of the ship sinking, release of pollutants from the tank of the sunken ship thereby being prevented. Should the ship sink, the hydrostatic pressure is applied via a strainer 56, restriction 51 and conduit 50 to a piston 46, thus moving the piston against spring 48 and pivoting latch member 40. The restriction 51 prevents momentary pressure, resulting from a wave breaking over the deck, from releasing the latch. A union 62, normally closed by a cover 63, can be used to salvage the tank contents of a sunken ship, a manually-operated lock 65 being actuated to prevent opening of the valve during operation of the salvage pump.

Abstract: 911,623. Road surfacing apparatus. WICKHAM, M. H. L. Dec. 1, 1958 [Aug. 29, 1957], No. 27181/57. Class 107. Road surfacing apparatus comprises a wheeled hopper 57 for depositing road surfacing material, a tractor which pushes the hopper and tows a finishing machine 53 which includes a screed vibrated by actuating means driven from a power take-off on the tractor. The finishing machine includes a rectangular frame formed by transverse members 1 and 2 of telescopic construction by which the width of the machine may be extended to end members 3. The frame is mounted on skids 5 by means of vertically extensible uprights 4 and the height of the frame and hence the thickness of the screeded layer is adjusted by means of screw jacks 15 connected between the frame and the skids. The screed 29 is supported by brackets from the rear transverse member 2 and is formed in two parts 32, 33 each of which e.g. 32 is connected to its supporting brackets 34, 42 by a bolt 38 which engages in a cylindrical bore in bracket 35 and bolts 34, 36 and 37 which engage in elongated holes in the brackets whereby when an unbalanced flywheel 30 mounted on the screed part is rotated the part is free to oscillate in a substantially up and down manner about the axis of bolt 38. The flywheels 30 are driven by belts 26 from a pulley 25 which is fixedly mounted on a shaft which extends forwardly through member 24 and is driven at its forward end from a power take-off on the tractor. The width of the screed may be extended by bolting an additional section to the outer edge of each screed part and the lower edge of the screed may be turned over to form a piped channel for the exhaust gases of the tractor which heat the screed when dealing with bituminous materials. The rear wall of the hopper 57 includes a vertically sliding door operated by an arm 67 by which the rate of material deposit is controlled and the deposited material is partially spread, before it is acted upon by the screed, by means of deflector plates 46 secured to the leading transverse bar of the frame.

Abstract: 913,014. Automatic speed-control systems. VOCKENHUBER, K., and HAUSER, C. Aug. 10, 1959 [Aug. 12, 1958], No. 27225/59. Class 38 (4). When a sound tape 11 is fed in the direction of an arrow 24, a loop 25 increases in size and a lever 9 moves downwardly under the influence of a spring 22 so that a wiper 6 engages a resistor 5 for energizing a film projector motor 1 through its field winding 3. The motor drives a roller 16 in the anti-clockwise direction, thereby decreasing the length of the loop until a balanced position is reached. If the sound tape is fed in the direction of arrow 26, the length of the loop is reduced whereby resistor 4 is connected in circuit with the motor 1 which operates in the reverse direction. Stoppage of the sound tape apparatus causes the wiper 6 to move to its neutral position to disconnect the motor 1, the wiper being carried by inertia into engagement with the resistor 5 for producing a counter torque. The sound tape is pressed on to the roller 16 by roll 17 mounted on lever 18 coacting with pins 45, 46, in slidable plate 19. A pin 20 in the lever 9 moves into a guide in the slidable plate for bringing the lever to its central position. In another arrangement the wiper 6 is actuated by differential gearing having elements respectively connected to the film drive and to the sound tape, Fig. 2 (not shown). In other arrangements the projector motor has a single-field winding only, Figs. 4, 5 (not shown).

Abstract: 993,314. Semi-conductor devices. WESTERN ELECTRIC CO. Inc. Aug. 3, 1961 [Aug. 17, 1960], No. 28272/61. Heading H1K. A semi-conductor device, operating in a manner analogous to a thermionic triode, comprises a semi-conductor wafer having a bulk portion # of one conductivity type and two spaced surface portions 13, 14 of opposite conductivity type forming PN junctions with the bulk portion, a dielectric coating 15 which at least covers the region between the portions 13, 14 and an electrode 17 on the coating. The material # may be of high resistivity P-type and the regions 13, 14 of N-type materials. With the region 14 biased positively with respect to 13, a space charge is created in the space 31 whose boundary intersects that of region 13 so that current flows between the two regions 13, 14. This may be varied by varying the potential on the electrode 17, the variation being due to two causes: (I) the electric field due to charge on the electrode 17 opposes or assists the movement of electrons out of portion 13, and (2) the charge on the control electrode 17 induces an equal and opposite charge in the #-region which is effective in the area 41 to move the point of intersection of 32 with the boundary 13a to vary the width of the current path between 13 and 14. Since the field due to electrode 17 penetrates only to a depth of 10,000  the thickness of the regions 13, 14 should be less than this or alternatively the distance between the regions should increase rapidly with depth so as to be greater than the critical distance at this depth. To construct the device a silicon wafer doped with boron is coated with silicon dioxide by heating in water vapour. Two suitable areas of the underlying surface are exposed by photoresist techniques and exposed to phosphorus pentoxide vapour to produce the N-type portions 13, 14. The residual oxide is removed by hydrofluoric acid and the wafer is then cleaned and reoxidized in steam. An aluminium electrode is then vapour deposited on the upper surface between the two PN junctions. The oxide layer is pierced through to the N-type surfaces and gold leads are bonded thereto in known manner. Specification 909,869 is referred to.
